Answer 2

Answer:

39b cm

Step-by-step explanation:

Explanation:

Given , a triangle -based oblique pyramid whose volume is 13$cm^{3}$.

Where pyramid is a polyhedrom with one polygon face  called the base and all the other faces are triangles which meet at the apex.

we know that ,

Volume of pyramid = $\frac{1}{3} bh$

where  b = base area of the pyramid

and h = height of the pyramid .

Step1:

∴ volume of pyramid = $\frac{1}{3} b h$

          $13 cm^{3} = \frac{1}{3} b h$  (  where volume of pyramid is given )

⇒  h = 13 ×3 × b = 39b cm

beause of value of b is not given  in the question

  ( where b is base area )

so, height = 39b cm

Final answer :

Hence , the height of the given pyramid is (39b )cm.
